c++ - Using boost for (pseudo-)random number generator of long double -

-

i'm trying use boost random number generation of long double (on 64bits machine).

at point use 

rng = boost::mt19937();

however, compiler argues on line 88 of boost/random/mersenne_twister.hpp, 

x[i] = (1812433253ul * (x[i-1] ^ (x[i-1] >> (w-2))) + i) & mask;

there implicit conversion shortens 64-bit 32-bit value...

i didn't specified if want long double or double... why arguing on that? because i'm using 64bits os?

is there simple solution problem? need long double generator... xd

thanks

the mt19937 32bit. defined in boost like

typedef mersenne_twister_engine<uint32_t,32,624,397,31,0x9908b0df, 11,0xffffffff,7,0x9d2c5680,15,0xefc60000,18,1812433253> mt19937;

for 64bit necessary use mt19937_64.

how can create excel report fixed header using japserreports? mean need header fixed when scroll excel file. this possible adding couple properties in jrxml file each report. take @ advanced excel features freeze panes. if wanted freeze after first column header (down left side basically) this: <statictext> <reportelement style="sans_bold" mode="opaque" x="0" y="60" width="104" height="20" forecolor="#ffffff" backcolor="#666666"> <property name="net.sf.jasperreports.export.xls.auto.filter" value="start"/> <property name="net.sf.jasperreports.export.xls.column.width" value="110"/> <property name="net.sf.jasperreports.export.xls.freeze.column.edge" value="left"/> </reportelement> &

i need duration of audio file series of voice announcements need play app. have added audio files resources , play fine. sample code below works perfect intended purpose: return duration of audio files. here code: float getdurationofaudioresource(locationenum loc, context context){ float duration = 0; try { mediaplayer mp; mp = mediaplayer.create(context, getaudioresource(loc)); duration = mp.getduration(); mp.release(); mp = null; } catch (illegalstateexception e) {e.printstacktrace(); logerror(25, "testdescitem:fault::could not open mediaplayer object audio resource.");} return duration; } here's weird thing. code called in main activity prepares set of audio instructions given test. there no errors within activity. second activity called, long string of errors on logcat. 03-07 13:23:43.820: i/actionlogger(21435): gentest_info_test #0 created. 03-07 13:23:43.830: i/actionlogger(21435): gente
